SPINNING-DISK EOE CRIME1NeilrrioHINEsA Application led September 30,1910.

To all whom 'it may concern.

Be it known that I, GEORGE IV. BEADLE, a citizen of the United States,residing at Bayonne, in the county of Hudson and State of New Jersey,have invented certain new and useful Improvements in Spinning-Disks forCrimping-Machines; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableOthers skilled in the art to which it appertains to make and use thesame.

This invention relates to disks for spinning in or crimping the edges ofcartons made of paper or like material, and has for its Object toproduce a disk of this nature which will not only crimp the edges ofpaper vessels, but will also upset or break down the same prior to thespinning operation as will appear more fully hereinbelow.

Disks of this nature may be used in a variety of machines but areespecially adapted for use in connection with machines such as thosedisclosed in my former application No. 564,602, filed June 2nd, 1910,and entitled Crimping-,machines for cartons.

To these ends the invention consists in the novel details ofconstruction more fully described hereinafter and particularly pointedout in the claims.

Referring to the accompanying drawings forming a part of thisspecification in which like numerals of reference refer to like parts inall of the views, Figure 1 is a plan view of a spinning disk made inaccordance with my invent-ion. Fig. 2 is a sectional view of the sametaken on the line 2-2 of Fig. 1; Fig. 3 is a plan view of a slightlymodified form of disk; Fig. 4 is a sectional view of the constructionshown in Fig. 3; Fig. 5 represents a still further modified form of theinvention, and Fig. 6 is a sectional view of the form shown in Fig. 5.

In the application above mentioned disks are disclosed in which aplurality of concentric spinning grooves are employed, the differentgrooves being intended to accommodate different sizes of cartons. It hasbeen found, however, in the actual use of this machine that a continuousconcentric groove does not perform the work required of it in a manneras satisfactorily as could be desired, and it has been further foundthat if the edge of the carton is rst broken down or forced in atdifferent points along its circumference so as to give it somethingSpeccation of Letters Patent.

like a corrugated appearance, the subsequent spinning operation willresult in a greatly improved job. Therefore in the disks 1 now tobedescribed, I retain the concentric spinning grooves 2, 3 and 4, but Iinterrupt said grooves at intervals by the radial slots or depressions5, as shown. The result of this construction is that when the disk 1 isforced longitudinally of the axis of the carton and against its edgeprior to the spinning operation, the edges 6 formed by the radial slots5 crossing the grooves 2, 3 and 4 will break down or force in the edgesof the carton at intervals. It further follows that later when thespinning operation begins, these broken down edges of the carton willlend themselves more easily to being folded over and spun into shapethan would be the case if the material were not previously broken down.

In addition to the above construction the spinning grooves are also inthis invention inclined toward the axis of the disk, as clearly shown inFigs. 2, 4 and 6, so as to form the beveled faces 7 on the outer wall ofeach of the grooves. These inclined faces 7 further serve to aid infolding in or rolling in the extreme outer edge of the carton, so thatthe subsequent spinning operation produces an exceedingly satisfactoryresult.

8 represents a back plate which is secured to the disk 1 and closes theradial slots 5.

The construction shown in Figs. 3 and 4, is similar to that in Figs.land 2, except the back plate 8 is omitted from these figures and thehub 9 of the disk is integral with the disk itself.

The form shown in Figs. 5 and 6 is likewise similar to the form shown inFigs. 1 and 2, but the back plate 10, disk 1 and hub 11, are integral asshown.

What I claim is:

1. A spinning disk for carton crimping machines having a plurality ofspinning grooves adapted to crimp the edge of the carton into thedesired shape; and means associated with said grooves for breaking downthe material of the carton prior to the spinning operation comprisingaplurality of radially arranged slots crossing said grooves,substantially as described.

2. A spinning disk for carton crimping machines having a plurality ofconcentric spinning grooves adapted to crimp the edge of the carton intothe desired shape; and a lplurality of radially arranged slots crossingsaid grooves, and forming abrupt shoulders on the Walls of said grooves,substantially as described.

3. A spinning disk for carton crimping machines provided With aplurality of spinning grooves having an outer Wall inclined to the axisof the disk; and a plurality of radial slots crossing said groovesforming abrupt shoulders With the Walls of the same GEORGE W. BEADLE.
